New strep throat risk score brings data together to improve care Posted: 04 Nov 2013 02:13 PM PST A new risk measure called a "home score" could save a patient with symptoms of strep throat a trip to the doctor, according to a new paper. The score combines patients' symptoms and demographic information with data on local strep throat activity to estimate their strep risk, empowering them to seek care appropriately.

Cutting-edge detector technology for astronomical observations developed Posted: 04 Nov 2013 01:27 PM PST Semiconductors have had a nice run, but for certain applications, such as astrophysics, they are being edged out by superconductors. Scientists have now developed a superconducting detector array that measures the energy of individual photons.

Electronic, internet health tools may decrease in-person physician visits Posted: 04 Nov 2013 01:23 PM PST An analysis of recent trends in digital health care and a review of the scientific literature suggests patients' future use of physician services will change dramatically as electronic health records and consumer e-health "apps" proliferate.

Repetition of rare events could reduce screening mistakes by security Posted: 04 Nov 2013 12:27 PM PST The failure to detect infrequent, but obvious security threats at airport screenings and other checkpoints may have less to do with incompetence or poor training than a human tendency to overlook rare events. But a researcher suggests guards could improve their detection rates the same way adults learn vocabulary words -- through repetition.

A better way to track your every move: Algorithm accurately tracks physical activity no matter where you carry your phone Posted: 04 Nov 2013 12:27 PM PST Physical activity tracking apps on smartphones are a potentially important tool for doctors who want to collect data and create treatment or intervention plans to improve the health of patients who struggle with activity and movement -- such as those with Parkinson's disease.

Diamond imperfections pave the way to technology gold Posted: 04 Nov 2013 12:27 PM PST Using ultrafast 2-D electronic spectroscopy, researchers have recorded unprecedented observations of energy moving through the atom-sized diamond impurities known as nitrogen-vacancy (NV) centers. Their results provide information on NV centers that is important for such highly promising advanced technologies as supersensitive detections of magnetic fields and quantum computing.

How common are habitable planets? One in five stars may have Earth-size, potentially habitable planets Posted: 04 Nov 2013 12:27 PM PST Astronomers analyzed all four years of Kepler data in search of Earth-size planets in the habitable zones of sun-like stars, and then rigorously tested how many planets they may have missed. Based on this analysis, they estimate that 22 percent of stars like the sun have potentially habitable Earth-size planets, though not all may be rocky or have liquid water, a presumed prerequisite for life.

Physicist discovers black holes in globular star clusters, upsetting 40 years of theory: Could there be ripples in spacetime? Posted: 04 Nov 2013 12:26 PM PST An astrophysicist was part of a team of researchers that discovered the first examples of black holes in globular star clusters in our own galaxy, upsetting 40 years of theories against their possible existence.

Computer-aided image analysis for breast tumor diagnosis Posted: 04 Nov 2013 11:24 AM PST Researchers hope radiologists will be able to routinely incorporate computer-aided image analysis and diagnosis in identifying tumor characteristics and forming patient-specific breast cancer treatment plans. Their approach uses data to identify how tumor characteristics apply to disease states, which could lead to the comparison of a tumor's characteristics with thousands of similar cases.

Designer piercings: New membrane pores with DNA nanotechnology Posted: 04 Nov 2013 09:37 AM PST A new way to build membrane-crossing pores, using Lego-like DNA building blocks, has been developed by scientists.

Dramatic end of plasma crystal experiment Posted: 04 Nov 2013 09:36 AM PST For seven years it delivered outstanding results for science and technology on the International Space Station, now the successful plasma crystal laboratory PK-3 Plus operated one last time. After undocking from the International Space Station the ESA Einstein transporter with the laboratory on board entered the Earth's atmosphere beginning of November and burned up - and PK-3 Plus produced its last plasma, a hot one. In June the operational phase of PK-3 Plus ended with a last series of experiments and with a spectacular finish; the scientists will still need some time to analyse these data.

Gravity and the robot satellite attitude problem Posted: 04 Nov 2013 08:26 AM PST Using an in-orbit robot to capturing a malfunctioning satellite that is tumbling out of control is currently just a theoretical idea. However, research inspired by nature could take us a small step towards making such science fiction science fact.

New tool may unveil inhabitable worlds Posted: 04 Nov 2013 08:24 AM PST A spectropolarimeter and a high-precision velocimeter optimized for both the detection of habitable Earth twins orbiting around nearby red dwarf stars and the study of the formation of Sun-like stars and their planets, was confirmed.

Bitcoin open to takeover, researchers discover with new algorithm Posted: 04 Nov 2013 08:22 AM PST A major flaw that has gone unrealized until now leaves the $1.5 billion Bitcoin market open to manipulation and a potential takeover, according to a new study by computer scientists.

Quantum 'sealed envelope' system enables 'perfectly secure' information storage Posted: 04 Nov 2013 07:12 AM PST Breakthrough guarantees "unconditional" security of information by harnessing quantum theory and relativity, and has been successfully demonstrated on a global scale for the first time.

New computing model could lead to quicker advancements in medical research Posted: 04 Nov 2013 07:10 AM PST A research team has now created a new generation of efficient data management and analysis software for large-scale, data-intensive scientific applications in the cloud. The goal was to keep up with the data deluge in the DNA sequencing space. The result has been a faster, more "intelligent" analysis of data.

New chemistry: Drawing and writing in liquid with light Posted: 04 Nov 2013 06:25 AM PST Researchers have manufactured photochemically active polymers which can be dissolved in water or certain alcohols.

Highly stable quantum light source for applications in quantum information developed Posted: 04 Nov 2013 06:25 AM PST Physicists have been successful in generating photons - the quantum particles of light – with only one color. This is useful for quantum information. The scientists have actively stabilized the wavelength of the photons emitted by a semiconductor thereby neutralizing the charge noise in the semiconductor.

Digital technologies improve remote rehabilitation, medical monitoring for patients Posted: 04 Nov 2013 12:52 AM PST Three projects have developed digital platforms aimed at the health care and hospital market that help to improve the medical monitoring of different segments of the population, such as the elderly or patients with chronic obstructive pulmonary disease (COPD).
